Types

type Watcher

type Watcher struct {
	// contains filtered or unexported fields
}

Watcher watches the browser process to attempt to identify situations where Chrome is crashing.

func NewWatcher

func NewWatcher(ctx context.Context, execPath string) (*Watcher, error)

NewWatcher creates a new Watcher and starts it. Returns only when the chrome PID it's watching has been identified.

func (*Watcher) Close

func (bw *Watcher) Close() error

Close synchronously stops the watch goroutine.

func (*Watcher) Err

func (bw *Watcher) Err() error

Err returns the first error that was observed or nil if no error was observed.

func (*Watcher) ReplaceErr

func (bw *Watcher) ReplaceErr(err error) error

ReplaceErr returns the first error that was observed if any. Otherwise, it returns err as-is.

func (*Watcher) WaitExit

func (bw *Watcher) WaitExit(ctx context.Context) error

WaitExit polls until the *Watcher's target process is no longer running.
